    "abstract": "For a one-dimensional chain of four nuclear spins (1/2) and taking into\naccount first and second neighbor interactions among the spin system, we make\nthe numerical simulation of Shor prime factorization algorithm of the integer\nnumber N=4 to study the influence of the second neighbor interaction on the\nperformance of this algorithm. It is shown that the optimum Rabi\u0027s frequency to\ncontrol the non-resonant effects is dominated by the second neighbor\ninteraction coupling parameter ($J\u0027$), and that a good Shor quantum\nfactorization is achieved for a ratio of second to first coupling constant of\n$J\u0027/J\\ge 0.04$.",
